Find GCD of Two Numbers using Recursion – Java Code

Write a Java program to find GCD of two numbers using Recursion. Given two input integers, we have to write a code to find GCD of two numbers using recursion. For this program, I assume you are familiar with the concept of recursion. If you don’t know about recursion then check my previous post on recursion vs iteration.

Recursion vs Iteration – Difference between Recursion and Iteration

Recursion vs Iteration. What’s the difference between recursion and iteration. Recursion and Iteration both are two different programming approaches. In some cases recursion is best suited and in some other cases iterative way of programming is good.

In programming, repeated set of instructions can be handled either by using recursive or iterative approach in your code. So which approach you choose and why. Let’s talk about recursion vs iteration.

Binary Search using Recursion in C

Multiply Two Numbers without using * (Multiplication Operator)

Write a C program to multiply two numbers without using * multiplication operator.

Given two numbers, both numbers are positive.  Write a program to multiply two numbers without using * multiplication operator.  Think for a moment how to solve this problem .

You can use multiple approaches to find the solution of a problem.

C Program to Reverse a Linked List using Recursion

Write a c program to reverse a linked list using recursion. Given a singly linked list, we have to write a code to reverse a linked list using recursion. This question is very important in terms of interviews.

In my previous post, I have explained C program to reverse a singly linked list. In this post, We are going to write a code to reverse a linked list using recursion.  If you are not familiar with the concept of recursion then check my previous tutorial on recursion vs iteration.

The time complexity to reverse a linked list using recursion is O(n). 

C Program to Print Fibonacci Series using Recursion

Write a C program to print Fibonacci Series using recursion. Given an input number, we have to write a code to print Fibonacci series up to that number using Recursion.

This question is very important in terms of technical interviews.

You can check my previous post for PHP script to print Fibonacci series. Before solving this problem, Let’s first understand what is Recursion?

What is Recursion?

In recursion, A function calls itself until the base condition is reached. Recursive code is much cleaner and shorter as compared to iterative code.
For better understanding you can check my previous post on recursion and what’s the difference between recursion and iteration.

For better understanding of  recursion concept, you can solve Objective Question on Recursion.

MCQ on Recursion – Recursion Objective Questions for Practice

MCQ on Recursion

Recursion is the most important concept in computer science. In my previous posts, i have written about binary search implementation using recursion and difference between recursion and iteration.

These MCQ helps you to understand the concept of Recursion.

1) Which Data Structure is used to perform Recursion?

a) Queue
b) Stack
c) Linked List
D) Tree

Binary Search Program in C using Recursion

Write a binary search program in C using recursion.

Binary Search is a searching algorithm that finds the value in a sorted array in O(logN) time complexity. In my previous post, I have discussed Binary search program in c using iterative approach. In this post, I am going to explain how to implement binary search program in c using recursion.

Recursion Concept with Example

What is recursion and how to use recursion in programming. If you are new to programming, then recursion concept is tough to understand. In this post, i’ll explain the concept of recursion with example.

What is Recursion ?

In Recursion, function call itself repeatedly, until the base condition is reached.  It’s a much preferred way to write cleaner and shorter code for many complex problems.

Through recursion, you can reduce complex problem into smaller version.
